Writ In Water, Runnymede

Formed from two circular rammed earth walls with a central oculus above a pool of water. The water reflects the words of Clause 39 of the Magna Carta.

The outer wall is 11 cubits high, the same dimension as the diameter of the inner chamber.

Writ in Water, commissioned by the National Trust in association with arts producers Situations, celebrates the enduring significance of Magna Carta.

An exterior doorway leads to a simple circular labyrinth, in which the visitor can choose to turn left or right to reach an inner doorway that opens out into a central chamber. Here the sky looms through a wide oculus above a pool of water, as reflective as a still font.

The sides of the pool are inscribed on the inner side, the water reflecting (much like the seal on Magna Carta itself), the reversed and inverted lettering of Clause 39 as the visitor moves round the pool to reveal its words.
